Abstract

The stage I work-hardening behavior of Invar Fe-Ni alloys was studied in tension in the temperature range from room temperature to 700 K. Work-hardening rate (WHR) is a function of temperature and has a peak at about 560 K. The anomalous strength is attributed to thermally activated cross-slip.
